  • Publication number: 20200161955
    Abstract: In the actuator, the viscoelastic members are arranged at positions at which the support body and the movable body face each other in the first direction, and the magnetic drive circuit drives the movable body in the second direction which crosses the first direction. The viscoelastic members connect the movable body and the support body together while having the thickness direction thereof in the first direction and extending in the second direction. Therefore, resonance caused when the movable body is vibrated can be restricted. Reproducibility of vibration acceleration corresponding to the input signals can be improved by utilizing the spring elements of the viscoelastic members in the shearing direction, thus enabling the actuator to vibrate with delicate nuances. Further, the viscoelastic members can be prevented from being pressed in the thickness direction and greatly deformed, therefore, preventing the gap between the movable body and the support body from greatly varying.

  • Publication number: 20200161038
    Abstract: In the actuator, the first end plate part of the first cover member in the support body is layered on one side in the first direction of the holder and faces the first yoke of the movable body from one side in the first direction. The second end plate part of the second cover member in the support body is layered on the other side in the first direction of the holder and faces the movable body from the other side in the first direction. Thus, the first viscoelastic member interposed between the movable body and the first end plate part in the first direction properly contacts with the movable body and the first end plate part. The second viscoelastic member interposed between the movable body and the second end plate part in the first direction properly contacts with the movable body and the second end plate part.

  • Publication number: 20200141514
    Abstract: A valve device is provided. In the valve device, a valve element is rotated about a support shaft, based on rotation of a valve element drive member to switch a through hole that communicates with an outlet formed in a valve seat to adjust a flow rate. The through hole opens in a bottom surface of a flow channel securing groove formed in the valve element. The flow channel securing groove has a long hole shape in which a width in a first direction being a moving direction of the valve element, is smaller than a width in a second direction orthogonal to the first direction. Thus, a region overlapping with the outlet is large as compared to a case where a perfect circular flow channel securing groove is formed.
